U.S. imports of sulfides of nonmetals (nesoi) and commercial phosphorus trisulfide (HS 281390) totaled $1.4M in April 2026, traded with 8 countries.
Importers of Sulfides of Nonmetals (NESOI) and Commercial Phosphorus Trisulfide paid $161K in duties in April 2026 — an effective duty rate of 12% on $1.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Sulfides of Nonmetals (NESOI) and Commercial Phosphorus Trisulfide imports of $1.4M in April 2026 ran 71% above the year-to-date monthly average of $834K.
Last updated: April 2026 dataPhosphorus sulfides including commercial phosphorus trisulfide (2813902000), arsenic sulfides (2813901000), and other nonmetal sulfides (2813905000 and 2813906000) serve niche but critical roles in match manufacturing, lubricant additive production, and specialty chemical synthesis. Italy leads US imports under this heading, followed by India and Japan, with Germany and the United Kingdom also among the top suppliers — a European-dominated supply base reflecting the specialty chemical manufacturing strengths of those markets. Importers should confirm the precise chemical identity of their product, as arsenic sulfides carry distinct toxicological and regulatory implications compared to phosphorus-based sulfides.

Arsenic sulfides are specifically enumerated under 2813901000, so any shipment of As₂S₃ or As₄S₄ must be declared under that line. Phosphorus sulfides including commercial phosphorus trisulfide fall under 2813902000, while remaining nonmetal sulfides are split between 2813905000 and 2813906000. The supplier's certificate of analysis identifying the compound by CAS number is essential to support the correct subheading declaration.
Arsenic sulfides are toxic substances subject to EPA TSCA certification requirements at entry. Importers must submit either a positive or negative TSCA certification with the entry filing. Depending on the volume and end-use, additional EPA or OSHA hazard communication obligations may apply, and consultation with a licensed customs broker or environmental compliance attorney is advisable before the first shipment.
